This invention relates to new and useful improvements in s ini gi Jipejoints and has for object the 'n'ovi ion of a swing inn joint wherehytwo tubular members may be operatively connected so an to peri'uit afree swi inn movement of one member relative to the other.

it further object of the provide a swiiuging conduit joint of simple,durable construction which may he manufactured at a low cost and whichwill perwit a tree swing, movement of one conduit relative to anotadapted to carry fluid under high pressure without leakage it. stillfurther object is to provide a swinging pipe joint havh a globulareapansion chamber into which the inlet pipe projects and to provide anew and improved packing gland comprising a novel arrange ment of partswhereby pacl'zing may be placed in position around the inlet pipewithout removing the swinging portion. of the joint therefron'n Anadditional object is to provide a swinging pipe joint having a practicalpacking gland provided with means where by the same may be adjusted tocompensate for wear and to provide additional means for securing theparts in assembled relation whereby an easily operable pipe joint isprovided which will stand great pressure.

The above and additional objects are accomplished by the novelconstruction, combination and arrangement of parts hereinafter describedand illustrated in the accompanying drawings wherein it have shown apreferred form of the invention, it being understood that the same iscapable of various adaptations and that changes and modifications may bemade or substitutions resorted to which come within the scope of theclaim hereunto appended.

The particular adaptation of the invention disclosed in the drawings isintended for use on the pumps or other ap nir invention is to Q-LlElordinarily used for dispensing fuel to automobiles or other motorvehicles but it is to be understood that the same may he used to providea swinging;- joint or conduit carrying steain water, gas air or otherfluid.

pipe joint constructed in accordance with this inventioi'i.

Fltigure 2 is a central, vertical, longitudinal sectional view of same.

Proceeding now to a detailed description of the invention with referenceto the particular adaptation thereof disclosed in the drawings, the numral 5 denotes a pipe which is internally tl'i'readed at the forward endthereof with the screw threads 6, where by it may he opcrativelyattached to the delivery nozzle of a liquid fuel serving device or anyconduit or other tubular member.

The tube is provided adjacent the forward end thereof with an annularflange 'l' which is formed thereon for a purpose herematter set forth.The numeral 8 denotes hollow globe which is provided with aner-zternally" threaded inlet extension 9 and with the ii'lternallytl'nreaded outlet extension Il Clheentei'isions 9 and 10 projectradially from the globe 8 with the axis of the inlet entensicn disposedat a right angle to the axis of the outlet extension.

the inlet extension is provided with a bore 11 adapted to snugly receivethe pipe which is fitted therein. The bore 11. is enlarged adjacent theouter end thereof to form the inclined offset shoulder 12, thus providing; a packing space or gland 13 between the pipe 5 and theinterior-face of the extension 9, in which is positioned the packing14;. The numeral 15 denotes a cylindrical ring which is fitted over thepipe 5 and fitted into the packing gland 13. The inner axial face of thering; 15 is oppositely inclined in relation to the inclined shoulder 12.The ring 15 is also pram "deal at the forward edge thereof with anannular tlange 15 which is arranged thereon to engage the forward faceof the extension 9 to prevent the ring 15 from being forced entirelywithin the gland 13.

The numeral it; denotes an internally threaded collar which isoperativcly threaded on the extension S). The collar 16 is pro vided atthe forward edge thereof with an inwardly projecting anniiilar flange l6which is fitted around the pipc and engages the forward edge of thering;- 15. The collar 16 is provided at the rear end thereof with anoutwardly projecting annular flange 17 which provided with oppositelyarranged flat faces for the purpose of providing); wrench engagingsurfaces,

ill;

To tightly pack the packing 1% around the pipe 5 the flange 16 isengaged by Wrench and the collar is operated to force the ring 15 intothe packing chamber 13, thus securel5 sealing the joint between theextension 9 and the pipe 5. The numeral 1? denotes a lock nut which isthreaded on the extension 0 and is operated against the collar 16 tosecure the some in position on the extension 91. The collar is alsoexternally threaded adjacent the forward end thereof with the screwthreats 16 and an internally threaded retaining ring l8isoperetivelythreaded; thereon. The retaining ring 18 isprovided'with a forwardlyprojecting annular lange l8 which is fitted around the pipe 5. lhe flane 7 is positioned between the flanges 16? and and means is thus novidedfor securing the pipe 5 against longitudinal movement in the extension9. The numeral 19 denotes 2 loch nnt which threaded on the collar 16 andis operated against the ringlS to secure the same in a prop'et positionthereon.

A hose 22 having an internall socket 21 is secured: on theconnettingnipple" 20 which is operatively threaded 1n the inletextension 10. An important feature of the invention lies in the factthat the collar 16 ma be unscrewed from the extension 9 J and the lobe 8inoved'outwardlv on the pipe t: I I U 5 and new aekin laced 1n the qland13 lv threaded:

es /es? Without entirely separating the parts. Ah tention is called tothe fact that the collar 16 may be operated on the extension 9 to exertgreat force on the packing lal and that the collar 18 may be operated onthe collar 16 end secured in place so that the flange 5' will he looselretained in place thus providing means whereby the joint between thepipe 5 d the globe 8 may he packed to l and g'nt pressure and withouthinthe lree rotary movement oi" the globe relat e to the pipe 5.

Hating thus illustrated my invention and d scribed the some in denil,what 1 c aim as new one oesire to secure by Letters ljatent in said inet ey n n 1 on said pipe, a coil :11 ed on said inlet extension, saidcollar zavnig an inwardly projec annular iange orojeel' a inwardly againaid pipe a second eollor threaded on the l collar the second collarprovided with an in- '\v: .rd y project rinnnlar flange, the flange onsaid pipe lining positioned between the la vs on said collars.
